`specification and shown in the accompanying drawings which form a part thereof:

The object of my invention is to provide a construction of machine for disintegrating linoleum compound and other substances, which shall embody simplicity, durability, easy repair and rapid cleansing.

My invention consists in a case having at the bottom means for receiving the disintegrated or pulverized materials, combined vwith a rapidly rotating beater device and a more slowly rotating perforated screen surrounding the beater device and inclosed within the case; further in so forming the case that it consists of two rigid side frames connected by a series of fixed cross bars, and the intervening spaces covered by plates, preferably of sheet metal, whose ends are clamped upon the cross bars by clamping devices carried by the fixed cross bars, whereby said covering plates may be bodily removed to expose the interior structure of the machine; further in forming the revolving screen of two circular flanged end frames, one of which is centrally open to admit the material to be treated, and a sheet metal screen stretched about the circular end frames and having clamping devices on its ends for tightening the screen in position and yet permitting of its easy removal for cleansing or when a screen of a different mesh or size of perforation is required, the said screen being of sheet metal it may be unclamped and drawn out, more or less flat, without dismantling the casing of the Inachine; further in the construction of olisintegrator drum and beaters whereby the latter may be easily replaced when worn without the necessity of removing the drum from the casing; further in the means for Y simultaneously rotating the beater drum and screen drum in the same direction and at different speeds.

My invention also comprehends details of construction which, together with the features above specified, will be better understood by reference to the drawings, in which:

Figure l is an end elevation of my improved disintegrating machine; Fig. 2 is sectional elevation of the same; Fig. 3 is a front elevation of the same; Fig. 4 is a front sectional elevation of the hopper end of the machine; Fig. 5 is a sectional plan view of my improved machine; Fig. 6 is a sectional plan view (on a larger scale) of the speed controlling and driving gearing; Fig. 7 is an elevation, with part broken away, showing the construction of the screen drum covering; and Figs. 8, 9 and l0 are sectional views of details.

The general construction of the machine embodies a revolving beater drum having a series of beater arms or blades, combined with an inclosing revolving screen drumy open at one end and into which the material to be disintegrated or pulverized is fed from a hopper, the said screen drum acting to continually lift the material and bring it into free position to be struck by the rapidly rotating beaters, an inclosing case surrounding the screen drum and having at its bottom one or more drawers or trays for receiving the pulverized and screened material, power means for rotating the beater drum, and gearing for causing the screen drum to rotate at a slower speed than the beaters, the construction being such that the machine may be fed continuously with materials to be disintegrated` and the action within the screen drum such that it is subjected to a cleansing action which prevents clogging of its perforations.

A feature of construction of my improved machine which makes it especially advantageous is, that every part of the machine may be exposed for cleaning or repairs without dismantling the fixed portions of the machine, and this result' is secured by having the outer case formed with sheet metal removable sections detachably clamped in position, and the screen covering of the screen drum formed of a removable sheet metal screen clamped in position about the adapted to stand upright from the floor. These side frames 2 are connected at top and at front and back on the horizontal diameter of the machine by fixed cross bars 3, which are essentially T shaped in cross section so as to form opposite grooved por tions on the outside.

37 are sheet metal covering plates having reinforcing bars 39 at their ends, and said ends rest in the grooves of the cross bars 3 and are clamped in position by cross clamp bars 40 and clamping screws 41 screwed into the cross bars 3. In addition to the plates 37, there are two additional covering plates 38, similarly reinforced at their upper edges at 39 and clamped in position by the clamp bars 40 and screws 41 (Figs. 2 and 3) and the lower ends of these plates 38 are guided and held in grooves 42 in the side frames 2 (Figs. 2, 3 and 10). By this construction, one or more of the covering plates may be removed without disturbing the permanent structure of the case. While I have shown an excellent form of clamping means for holding the plates in position, it is to be understood that I do not restrict myself to this particular means as any other means capable of holding the plates in position may be employed.

8 is the beater shaft which extends centrally through the machine and journaled in the bearings 6 and 7 and is provided at one end with the driving belt wheel 9. Secured rmly to this shaft is a hub or drum 10 which is provided with four Tshaped sockets at each end into which T-shaped beaters 11 and 12 are received and clamped in position by end heads 13 secured in posi tion by bolts 14 extending through the drum 10 and said heads 13, as shown in Figs. 2 and 5. The opposite beater arms 11 are straight, whereas the opposite beaters 12 are curved outward so that their ends travel in a different path from the beaters 11. In this manner the beaters 11 and 12 travel in four parallel planes and are thus distributed transversely of the inclosing screen drum 15, as will be readily understood by reference to Fig. 5. It is evident that beaters may be readily replaced when worn or broken by simply removing the nuts of the bolts 14 and withdrawing the heads 13 from the socketed ends of the beaters. As much wear comes upon the beaters, it is most important that they shall be easy of replacement when necessary.

Surrounding the beater drum and beaters is the screen drum 15, consisting of the cylindrical end plates 1G and 19 and the connecting screen covering 30. Referring to Fig. 5, the end plate 19 has a hub 2O journaled on the shaft 8 and also within the bearing 22 in a support 21 on the frame 2. End plate 1G is open at the center and has a flange 17 which is journaled on a Babbitt bearing 18 supported by a tubular flange 4 secured upon the inner face of the side frame 2. Both of the end plates 16 and 19 are fianged at their outer ends (Fig. 5) and upon these anges the perforated sheet metal screen covering 30 is stretched. I prefer that the side edges of this screen cov ering be left plain (Fig. 7). The ends of the sheet metal, of which the covering 30 is made, are overlapped and respectively provided with fianges 31 and 32 which are connected by tension bolts 33 (Figs. 7 and 8). By clamping the screen covering upon both the end plates 16 and 19, the rotation of the latter will cause the entire screen drum to rotate.

The material to be disintegrated is fed into a hopper 5 on one of the end frames 2 (Fig. 4) and from the hopper it passes through the tubular flange 4 and into the interior of the screen drum 15. The cylindrical flange 4 may be provided with an inclined floor 45, as a continuation of the ioor of the hopper, if so desired. In this way the material is delivered within the screen' drum and to the beaters with freedom during the normal operation of the machine.

By being able to continuously feed the machine, it does not become clogged or over loaded and hence the rapidly moving beaters have full opportunity of forcibly striking the material with a clean impacting blow as distinguished from pushing or churning it, the result being a rapid and perfect disintegration at a minimum cost.

Below the screen drum are arranged two drawers 43 and 44, the former receiving the disintegrated and screened material and by which it may be removed at intervals. During the act of removal the machine continues to operate and the material falling from the screen is received in the lower drawer 44. However, the upper drawer may be emptied a half dozen times to each emptying of the lower drawer. The employment of the two drawers enables, however, the operation of the machine to be continuous and hence economical.

As before stated, the screen drum 15 is.

rotated at a slower speed than the beaters and their shaft 8 and to secure this result, I employ the speed gearing shown in Fig. 6. This speed reducing gearing is made as follows The beater shaft- 8 has keyed to it a.

gearing may be used if so desired. As shown, this gearing is inclosed Within an oil box consisting of a lower part 28 carrying the bearing 7 and attached to the side frame 2, and an upper cap or cover 29 detachably secured in place to keep out the dirt and to prevent escape of the lubricant.

My invention may be used for disintegrating or pulverizing various materials or compounds in a speedy and efficient manner and hence, while I have used it more especially for the disintegration of linoleum compound or mixture preliminary t-o its being put into the plastic condition, I in no wise intend to restrict myself in the use of my invention.

A most important feature in my improved disintegrator resides in the capacity for quickly changing the screen whereby finer or coarser apertured screens may be employed.

I have shown my invention in the form which I have found most excellently adapted for commercial practice, and while I prefer the same, it is evident that the details thereof may be modified without departing from t-he spirit of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent, is

having cross bars secured at a short distance from each end so as to leave portions of the plate beyond the cross bars, and clamping bolts connecting the cross bars for drawing them toward each other and causing the ends of the plate to overlap intermediate of the cross bars.

2. A screen drum plate for a disintegrator, consisting of a long flexible plate having cross bars secured at a short distance from each end so as to leave portions of the plate beyond the cross bars, and the body of said plate between the cross bars being uniformly perforated throughout its length and width with the exception of the surface adjacent to the side edges which is unperforated for a short distance from said edges, and clamping bolts for drawing the cross bars toward each other and causing the ends of the plate to overlap intermediate of said cross bars.

In testimony of which invention, I have hereunto setmy hand.
